The Halifax MP's attempt to have Iraq debated at the conference was earlier blocked.

Mr Wolfgang shouted out as Mr Straw told delegates: "We are in Iraq for one reason only to help the elected Iraqi government build a secure, democratic and stable nation."

Mr Straw had also compared Iraq to Germany after the World War II, where it had taken four years before elections were held.

'Nice people'

The party member of 57 years' standing told the BBC Two's Daily Conference Live programme: "These two toughies came round and wanted to manhandle me out.

"I said: 'Do you want me to leave? I will leave, you don't need to manhandle me.' Physically, I am not too well, so I said I would follow them.

"Most of the Labour Party stewards are very nice people. One or two people lend themselves to this nonsense.

"It makes me feel that the people who resort to these tactics are very unsure of themselves and they are on the losing side."

Outlining the measures taken by its officers, Sussex Police said: "The protocol in this situation is that a police officer is called.

"The police officer attended and asked the man to wait for a member of the Labour Party.

"We wish to stress that the delegate was not arrested or searched at any point during his brief interaction with the police officer and that it is a matter for the Labour Party to decide who they allow into their conference."
